-----------------------------------
Summary: change the bookieServer cmdline to make conf-file and
option co-exist
Key: BOOKKEEPER-966
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-966
Project: Bookkeeper
Issue Type: Improvement
Reporter: Jia Zhai
Assignee: Jia Zhai
Currently, when using bookieServer cmdline to start a bookie, you will either
give it a cofiguration file by "-c booke.conf"; or add some options like
"<bookie_port> <zk_servers> <journal_dir> <ledger_dir [ledger_dir]>" in a fix
sequential.
It may not satisfy some of the requirement. So changed it to be co-exist for
configuration file and options.
By this change, it will first use settings in configuration file; and then use
options to overwrite some of the settings, if there are some options provided.
Here is an example after this change:
BookieServer -c bookie.conf -z localhost:2181 -m /bookkeeper/ledgers -p 3181 -j
/mnt/journal -l "/mnt/ledger1 /mnt/ledger2 /mnt/ledger3”
Here, in this command:
-z is for “Zookeeper client instance”;
-m is for "Zookeeper ledgers root path for bookies";
-p is for "bookie service port exported";
-j is for "bookie journal directory";
-l is for "bookie ledgers directories".
